Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

A valuable, impressive, and portable product that saves time and has great scalability and stability
It just saves time. We have run into situations where contractors come in, and they plug in a WiFi device that is handing out DHCP addresses, which affects the rest of the network. To be able to quickly identify from where the problem is originating, you need a network tool that can identify the device that is doing this. It just brings into clear focus the exact issue when there is a problem or outage. When there is a crisis and you've several people wanting to know an estimate of when things are going to be back up and running again, you need to have answers. I have been at places that didn't have a tool like that. I know one place that had an outage for almost a week, and it was craziness. It turned out to be just a bad cable. That's all it was. They were having trouble with their email server, which was an on-premise email server, but emails were taking six hours to appear. The whole problem was because of a bad network cable. When I plugged in the Fluke analyzer, it analyzed and told me immediately that there were transmission errors on this one port from one switch. It told me this within 10 minutes. It is an incredible product.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"Nagios is great for verify quality and quantity in a datacenter."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution's most valuable feature is its simplicity."
"An excellent solution that is easy and intuitive to implement."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"We are using this product to improve our view of what is happening with the packets."
"OptiView XG helps us troubleshoot problems faster than we would normally be able to."
"When I plugged in the Fluke analyzer, it analyzed and told me immediately that there were transmission errors on this one port from one switch."
"The 10 GigE connectivity and ClearSight are the most valuable features for us."
"We were able to find out that there was actually double acknowledgments coming from one of the devices, and we were able to share that with the coders and ultimately get it fixed."
"When we do a capture, it gives us the details of where the problem is and what it could be."
"We switched to OptiView to be a little bit more flexible."
"We use it for all of our predictive Wi-Fi designs, and we get standards reports so we're able to do more of the designs more quickly and more consistently."
 

Cons

"Business services monitoring is still really basic."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"However, it is a bit complex and difficult for a first-time user."
"Its simple deployment but complexity comes once you have to import more plugins."
"For some, it may be difficult to deploy."
"Nagios XI can improve its GUI for users with a new look."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"We found that when we used the wireless section of the AirMagnet, we used to have a laptop dedicated to AirMagnet and it actually ran smoother on the laptop."
"Ease of updating, automated updating. Basically, based on the unit right now, maybe get it to be a little bit smaller, lighter."
"The licensing cost needs to improve since it is very expensive, especially the licensing and maintenance costs."
"Hardware is unreliable. It's already crashed on me several times."
"Also, the overall weight of the product is a lot to carry around for a long period of time."
"That would probably be something I'd want to add on."
"I think that the discovery of a network can be improved if the OptiView would recognize more kinds of devices independent of the manufacturer."
"I had some problems generating reports."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"Its price was a bit excessive. The device that I had died. It is under warranty, and they want $20,000 for another one. I just don't want to spend that kind of money, so I'm trying to find an alternate solution. They have annual maintenance on it, which probably was 10% a year, so it all starts to add up."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
